I wanted a cheap X58 motherboard for my i7 920 cruncher that has been sitting around since I replaced it with another i7 970. I had a ASRock X58 Extreme last year and it did the job. Not going to push this board to hard at all as it is just going to be a dedicated crunching rig

No idea. I've got the stock 970 heatsink on and it sucks balls. Idle is nearly 10º higher over the CM212+. It gets super hot, super fast. The fan spins so freakin fast but the fin spacing is so tight no air gets through. Lame...

whoops forgot that I've got a new Heatsink(x2 actually) and pair of fan controllers to play with
